The structural compartmentaion of mammalian cells

In an extremely concise summary I will outline the key features of ATP production and where in the mitochondria that these stages occur. Protein and glycolipid components of human erythrocyte membranes. The nucleus usually the largest organelle in a mammalian cell, and like almost all other organelles is encased within a phospholipid bilayer.

This chain will later become a protein. This is known as transcription. The endoplasmic reticulum is specialised for protein processing and lipid biosynthesis.

The nucleolus is responsible for ribonucleoprotein maturation, where ribosomal RNA is transcribed and combined to proteins to form nearly complete ribosomes [9]. Many chromatin fibres further condensed make up chromosomes. More Essay Examples on Science Rubric As shown in Fig 1, the bilayer is permeated with different types of protein, glycolipid etc.

On the interactions of lipids and proteins in the red blood cell membrane. This may not be the complete list of references from this article. Selected References These references are in PubMed.

The rapid intermixing of cell surface antigens after formation of mouse-human heterokaryons. It is called rough because of the presence of ribosomes makes the surface of the membrane look rough, unlike smooth ER, which lacks the ribosomes so the membrane looks smooth.

Within the nucleus is where chromatin is found. Calorimetric evidence for the liquid-crystalline state of lipids in a biomembrane. Rhodopsin content of frog photoreceptor outer segments. Erythrocyte membrane sulfhydryl groups and Rh antigen activity. Rough ER is composed of a large but convoluted flattened sac.

The main function of the smooth ER is the production of lipids and the metabolism of compounds such as the breakdown of glycogen into glucose. The ribosome is made up of large complexes of RNA and protein.

These cristae are long finger-like extensions from the inner membrane into the centre of the organelle.

Multiple protein components of mammalian cell membranes. X-ray diffraction studies of phase transitions in the membrane of Mycoplasma laidlawii. As depicted in Fig. Endoplasmic reticulum ER can come in two forms.

It also contains enzymes responsible for the metabolising of drugs. Biochem Biophys Res Commun. It is made up of proteins and nucleic acid. Between the inner and outer membrane is the intermembrane space, and inside the inner membrane is called the matrix.

Ferritin-conjugated plant agglutinins as specific saccharide stains for electron microscopy: The inner membrane, whilst following the outer membrane around the majority of the organelle, has lots of cristae.

At points this double membrane touches, forming nuclear pore complexes. Chromatin is DNA strands wound around histones [3]. A single mitochondrion itself has two structurally and functionally distinct membranes. Studies with red blood cell membranes.The male reproductive system consists of the primary sex organs, the two testes and a set of accessory sexual structures.

Describe the structural compartmentation of mammalian cells

The adult mammalian testis performs two important functions, spermatogenesis. describe the structural compartmentation of mammalian cells and the differing functions of these compartments? Mammalian cells are eukaryotic this means that all of their cells have common components, membrane bound organelles which prokaryotic cells do not this is shown in figure 1.

Dec; 61 (4)– [PMC free article] Lenard J. Protein and glycolipid components of human erythrocyte membranes. In conclusion mammalian cells have a very complex structure containing internal membrane-bound compartments that are specialised to specific tasks.

This structure allows eukaryotic cells to maintain different environments in different sections of each cell, and assists with metabolic control by keeping enzymes, substrates and regulators in separate locations with access between them.
